ANSI X9。79-2013解决了非对称密钥的管理和安全问题，以保护金融信息和其他相关数据，不受非对称算法、方案或公钥加密协议的影响。非对称密钥对由使用非对称密钥生成算法共同创建的数学相关私钥和公钥组成。只有公钥（通常封装在证书颁发机构颁发的X.509证书中）被分发给依赖方。相应的私钥必须由发起方保留。

ANSI X9.79-2013 addresses the management and security of asymmetric keys for protecting financial information and other associated data independent of the asymmetric algorithm, schemes or public key cryptography protocol. An asymmetric key pair consists of a mathematically related private key and public key that are jointly created using an asymmetric key generation algorithm. Only the public key (often encapsulated within an X.509 certificate issued by a certification authority) is distributed to the relying party. The corresponding private key must be retained by the originating party.
